APPLIANCE FOR SUPPLYING RIBBON GOLD T0 ROTARY-DISK GILDING-IOOLS.

To all whom it may concern;

Be it known that we, JOHN C. MERWIN and J OHN W. DONOVAN, bot-h citizensof the United States, and residing in the city of Holyoke, Hampdencounty, Massachusetts, have invented certain new and useful Improvementsin Appliances for Supplying Ribbon Gold to Rotary-Disk Gilding-Tools:and we do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

Our invention relates to an appliance for supplying ribbon gold torotary disk gilding tools, and consists in the construction andassociation of elements hereinafter fully described and thenparticularly pointed out in the claims which conclude this description.

In the accompanying drawing Figures 1 and 2 are side elevations of ourimprovement looking from opposite sidesFig. 3 a detail broken sectionaledge elevation of the gilding tool-Fig. 4 a detail elevation of theelement which supports the gold ribbon and distributes the same to therotary disk-Fig. 5 a section at the line 00, 00, of Fig. 2 but showingin plan the frame that supports the gilding material, and Fig. 6 a sideelevation of a modified form of our improvement.

Similar numerals of reference denote like parts in the several figuresof the drawing.

In appliances of this description it is necessary that the gilding toolshould be heated in some suitable manner, but our invention has nothingwhatever to do with such heating and we have merely shown an approvedform of device in which the heating is effected by electricity, but wehave shown no details in this respect nor will we enter into anydescription of the heating elements employed.

The main object of our improvement is to deliver the gold in ribbon formtothe gilding disk and at the same time to wind up the paper used as abacking to the gold ribbon; also, a further object of our improvement isto so support the reel of paper backed ribbon gold and to so wind thepaper after the distribution of the gold along the gilding disk, that itis impossible to tangle or disarrange either the paper or the gold,

all of which will be readily understood from the following description 1is any suitable handle having at its lower extremity an integral cheekplate 2.

3 is the gilding diskAthe electric heater, 5 the cover plate to theheater, 6 a metal plate, 7 a friction ring and 8 a keeper ring, allofwhich parts are arranged concentrically, and held together by means ofscrews 9. These screws are passed through registering openings in thering 8, the plates 6 and -5, and the disk 3, and their extremities areengaged with nuts 10 which are tightened firmly against the outer faceof said disk. It will be observed from Fig. 3 that the aforesaid screwsdo not engage ring 7, that ring encircling an annular boss or hub onplate 6 through which the screw openings extend. In consequence, thering 7 which is interposed between ring 8 and plate 6, will normallyrotate with disk 8, but may be held stationary, in the mannerhereinafter described, without preventing said disk from rotating.

The periphery of the gilding disk 8 may have any suitable pattern formedthereon, and is here shown as continuously grooved, so that the goldribbon applied thereby will be firmly ironed in two parallel lines, themiddle portion of the ribbon between said lines being subsequentlyremoved with a brush.

12 is a bolt having a head 13, and upon this 'bolt are journaled thegilding disk and the parts 5, 6 and 7 directly associated thereto, theend of the bolt extending through the cheek plate 2 and handle 1 andbeing engaged by a nut 14 which is tightened firmly against the outerface of said handle, so that it will be readily understood that the saidrotary parts are supported by the ,lower extremity of the handle.

15 is an arm extending radially from the friction ring 7 and projectingbeyond the edge of the disk 3.

16 is a pin having an integral collar 17, and 18 is an arm carrying atits outer extremity a bearing 19, said pin extending through the otherend of said extension 18 p and also through the upper portion of theextension 15 and being engaged by a nut 20 tightened firmly against theface of arm 15 so as to confine the arm 18 between said collar and saidarm 15, thereby allowing arm 18 to be revolved about said pin but withconsiderable friction.

The parts 15, 16, and 1S constitute a frame'for carrying the reel ofribbon gold, the paper winding arbor and an oil roll which will now bedescribed.

21 is a support to which the reel (4 of paper backed gold ribbon isjournaled by means of a hollow screw 22. A finger 23 extends from thesupport and bears with a slight friction against the side of the reel ofpaper backed gold ribbon so as to prevent the same from revolving toofreely and the screw 22 is passed through this finger and the back ofthe support.

24 is a winding arbor having spaced cheek plates 25, said arbor beingjournaled at the other end of the support 21, which latter is .mountedon the frame by passing the pm 16 through the hollow screw 22 so thatthis support 21 will swing by gravity from said pin. hen this support isin position on the frame as above described, the winding arbor will restby gravity against the edge of the disk 3 and the cheek plates 25 willembrace said disk thereby preventing any lateral displacement of Saidsupport.

26 is an oil roll of any suitable material such as felt or any otheranalogous substance which roll is journaled around the bearing 19 and byswinging the arm 18 downwardly until the oil roll has a good contactagainst the edge of the disk the latter will be oiled preparatory to thedelivery of the gold thereon as will be hereinafter more particularlydescribed.

27, 28, are stops that extend from the ring 7 on opposite sides of thehandle 1, these stops being omitted from Fig. 3 for the sake ofclearness.

The operation of our improvement is as follows :The workman attaches,byfmeans of paste or otherwise, the end of the paper backed ribbon ofgold to the winding arbor 24 and then grasps the handle 1 and rolls thedisk '3, thus winding the material around the arbor 24 so as to presentthe gold ribbon c to the oiled disk 3, and the continued revolution ofthe disk thereafter will transfer the gold to the article to be gilded,which, in the present instance, is a book cover or back. As fast as thegold leaves the paper back and is transferred to the disk the paper 6will of course be Wound upon the arbor 24 and as the diameter of thewound paper is constantly increasing the support 21 will rise upwardly,swinging from its pivotal point.

Of course, the oil roll may be located at any other portion of the disk,and might be journaled to the handle if desired, and we therefore do notwish to limit ourselves to the provision of any oil roll on the frameitself. The oil might be applied by the fingers of the workman, or inany other suitable way, as by a brush, for instance, and it is thereforenot at all essential that this roll shall be supported on the frame. Asthe workman rolls the. disk along the article to be gilded the stop 27will strike against the bottom of the handle 1 and thereafter the diskalone will revolve while the frame will remain stationary. If this stop27 were not provided the frame and support would be carried by therevolution of the disk downwardly until they abutted against somestationary element such as the article to be gilded, and of course thiswould be fatal to the successful operation of our improvement. On thereverse'movement of the disk, whet-her accidental or otherwise, the stop28 abuts against the upper side of the handle and thereby prevents thearm 18 or the frame from coming in contact with such handle. 7

In gilding a round surface such as the hack of a book, after the workmanhas rolled the disk across such back and prior to another similargilding operation, he merely revolves the disk in the'reverse directionso as to return the disk to its initial position, after which it mayagain be placed in contact with the rounded surface to be gilded withoutlosing any appreciable amount of the gold. When the 'diskis turned inthe reverse direction'it will of course carry with it the frame and thesupport for the gilding material and therefore the latter will not bedisturbed in the slight est degree.

The appliance illustrated in Figs. 1 to 5 is suitable for gildingstraight surfaces or curved surfaces, but for straight gilding alone itis not necessary that the frame should be capable of a rotary movementindependent of the disk, and therefore in Fig. 6 we have illustrated amodification in which the friction ring, is dispensed with and an arm'29 is rigidly secured to the end of the handle .and extends upwardlyprecisely after the manner of the extension 15, and the pin 16 issecured to the upper end of this arm in the manner heretofore describedwith respect to said extension. But in this construction illustrated inFig. 6 any reverse movement of the disk will cause the paper to unwindfrom the arbor, the result being that the gold ribbon would probablybecome broken.

7e therefore do not wish to be limited to 8 any particular mannerofsecuring the ele-' ment which forms aframe on which the rollof gildingmaterial and the'paper winding arbor are supported.

V 30, 31, are the insulated electrical conductors which lead to suitablecontacts .(not shown) whereby the heating of the parts 4 and 3 iseffected, and in this connection we would call attention to the factthat our improvement is particularly advantageous,

' said element the combination,

since the frame and support 21 become quite hot, but it is merelynecessary when a reel of the gilding material has become exhausted toremove the support 21 and substitute in its place another similarsupport with the gilding reel in proper assembled position, and itsextremity secured to the winding arbor.
